There are two ways to meet a budget.
The one I have become most familiar with in the last couple of years is go over the budget and cut expenses.
Government hasn't even had a budget, much less cut costs, even though maintaining current revenue and dissolving the programs which are beyond the scope of any sane interpretation of the Constitutional Authority of the Federal Government would likely pay off the DEBT in our lifetimes (and I'm an old fart).
The other one (not always available to us Citizens) is to make more money.
For short term problems the judicious use of credit may be in order, with a plan to pay it off before money is borrowed. That is a stopgap, however, and not a long-term solution.
That's why I'm such a strong proponent of eliminating or substantially cutting corporate income taxes. Such a move helps businesses make more money (by keeping more of what they earn). That in turn has a ripple effect on both employees (more get hired, or get raises) and consumers (products they purchase aren't marked up to account for the producer's tax bill.)
The problem with cutting or eliminating the corporate income tax is ideological opposition by the left. But the left also loves to tax the rich. To me, Bannon has the germ of a good idea - if conservatives can't get their act together, rather than abandon the idea of corporate income tax cuts, work with centrists on the Dem side to achieve them. And what will the Dems want in exchange for cutting the corporate income tax? Why, increased personal income tax rates on the rich.
I think that's a backup strategy worth considering. Ideally, it wouldn't be necessary - all the savings needed to cut the corporate tax rate can and should come from the block-granting of Medicaid. But that requires GOP unanimity that simply isn't there. So what is Trump to do? If conservatives won't dance, get another partner.
